Print without continuous updates in scroll bar

[Austiner87]

Hi NT8 support,

I am looking for a method for the print function to simply update one line continuously as opposed to continue to output each instance of my print so that it scrolls down with many lines. Is there any way for an output to just update one single line each time the print instance occurs to where that number updates without continuously printing down the window?

Normal Print looks like:

In Ninjascript Output Window
Variable: 100
Variable: 105
Variable: 107
etc
etc

Looking for:

In Ninjascript Output Window
Variable: 100 (and this single line updated to, say 105 on the next instance)
(does not print another line here on next instance but updates first line)

Thank you!

Hello Austiner87,

Thanks for your post.

You can issue ClearOutputWindow() before each print.

This method is demonstrated in the example indicator SampleLevel2Book which provides what looks like updated lines:

Ask Book
Ask Price=11635.25 Volume=1 Position=0
Ask Price=11635.75 Volume=1 Position=1
Ask Price=11636 Volume=2 Position=2
Ask Price=11636.25 Volume=2 Position=3
Ask Price=11636.5 Volume=2 Position=4
Ask Price=11636.75 Volume=5 Position=5
Ask Price=11637 Volume=3 Position=6
Ask Price=11637.25 Volume=2 Position=7
Ask Price=11637.5 Volume=1 Position=8
Ask Price=11637.75 Volume=1 Position=9
Bid Book
Bid Price=11634.25 Volume=3 Position=0
Bid Price=11634 Volume=1 Position=1
Bid Price=11633.75 Volume=2 Position=2
Bid Price=11633.5 Volume=4 Position=3
Bid Price=11633.25 Volume=1 Position=4
Bid Price=11633 Volume=4 Position=5
Bid Price=11632.75 Volume=2 Position=6
Bid Price=11632.5 Volume=4 Position=7
Bid Price=11632.25 Volume=2 Position=8
Bid Price=11632 Volume=2 Position=9

but in reality, it is just clearing the window before printing each update all of the lines.
